Walking action of avatars

[SivaKartheek]

Hello Everyone,

Good Morning , I am having some problem with walking action. Actually I arranged 40 pedestrains in a list and then i have a data of 40 avatars in a xml file. Some avatars are moving properly and then reaching destination but some of them are rotating some time and then reaching destination .( I don't Understand why they are rotating like that)
if anyone know regarding this , can you please give me an idea why the avatars behaving like that

I have one more question , Is it possible to arrange parallel walking action of avatars ?? if so where can i get the information this

I hope some one will help me with this regards

thank you in advance
